I have some spare parts and i want to build a 8 bit computer out of it.
P8080A, Z80A or 6502
18*2KiB SRAM, 9*256Kib or 4*2Mib nybble
8255 to extend the 16bit address to 24bit tops, i think i should round it out at 4MiB which is 22bits which makes windows of 16KiB.
this would then run in mode 1 and the other ports well i have some ideas for them.
8228 as a bus divider so the system and the video memory will be in the sam address space.
6845 or 8275 CRTC.
So many things i can do with it all so many directions.
